Gray tufts all over driftwood and spreading
I don't think its an algae but I have these gray tufts all over my driftwood. I noticed it on the large rocs and now the filter intake. I have some close up photos but I can't find my card reader. They are dark gray and in somecases have some green on them.
None of the fish seem to touch it. And I have Flagfish and wild molles in there that eat everything.
Any ideas while I look for the card reader?
